BETA PICTORIS PLANETS? LIFE? OR WHAT?JARAASTRONOMY 102 SEC 013The ultimate question is Is there a possibility that bearing might exist on aplanet in the Beta Pictoris corpse? First, one must ask, Are there planets inthe Beta Pictoris system?. However, that question would be impossible to answerif one did not answer the most basic questions first Where do planets comefrom? and do the key elements and situations, compulsory to form planets, exist inthe Beta Pictoris system?.To understand where planets come from, one has to first look at where theplanets in our solar system came from. Does or did our star topology, the sun, have acircumstellar dish antenna around it? the answer is believed to be yes.Scientists believe that a newly formed star is immediately surrounded by arelatively dense cloud of gas and dust. In 1965, A. Poveda stated, That newstars are likely to be obscured by this envelope of gas and dust (1). In 1967,Davidson and Harwit hold with Poveda and then stipulation ed this occurrence, the cocoon nebula (1). Other authors have referred to this occurrence as, a placental nebula (1), noting that it sustains the growth of planetary bodies.For a long time, even before there was the term cocoon nebula, planetaryscientists knew that a cocoon nebula had surrounded the sun, long ago, in orderfor our solar system to form and take on their currents motions (1).In 1755, a German, named Immanuel Kant, reasoned that gravity wouldmake circumsolar cloud contract and that rotation would flatten it (1)." Thus,the cloud would assume the general shape of a rotating disk, explaining the factthat the planets, in our solar system, revolve in a disk-shaped distribution.This idea, about the disk-shaped nebula that was formed around the earlysun, came to be known as the nebula hypothesis (1). Then, in 1796, a Frenchmathematician named Laplace, proposed that the rotating disk continued to cooland contract, forming planetary bodies (1). Also, when investigating theev olution of stars, it was proposed that a star forms as a central condensationin an extended nebula... The outer ramify remains behind as the cocoon nebula (1). During the same study it was also indicated that under various conditionssuch as rotation, turbulence, etc. the nucleus of the forming star whitethorn divideinto two or more bodies orbiting each other (1). This may be the explanation asto why more than half of all star systems are binary or multiple, rather thansingles stars, like ours, the sun.This same fragmentation may also form bodies too small to become stars.
